I have a Remington 760 30-06 made in 1953. (The old 7600.) And when I first got it all I heard was that pumps are crap, they will never group tight, blah, blah,blah.
Well, that rifle still shoots a tight group with reloads 53 years later and has killed everything from wood chucks to moose. I think good or bad is more dependent on the individual rifle rather then what model it might be. Of course it helps if we aim them correctly too. And as I get older that gets harder.
